Technical Field

[0001] The present application relates to the technical field of switch cabinets, and in particular to a protective cover for an isolating switch. Background Art

[0002] An electric control cabinet is a closed or semi-enclosed metal cabinet that protects electrical equipment and is equipped with multiple functions such as detection devices, switch control devices, and auxiliary equipment. Electric control cabinets are generally equipped with a large number of electrical equipment such as main circuit boards, relay boards, dashboards, and power supply cables. These electrical equipment must not only comply with the basic specifications for electrical equipment and meet the requirements for the normal operation of the power system, but also be easy to use and maintain on a daily basis and have a certain degree of electrical safety and stability.

[0003] Among them, an isolating switch is generally installed on the surface of the electric control cabinet. The isolating switch is used to isolate the power supply to ensure safety. During the working process, the isolating switch is used to reliably isolate the part of the high-voltage electrical device that needs to be repaired from other live parts, so that the staff can work safely without affecting the normal operation of the rest of the parts.

[0004] Regarding the above-mentioned related technologies, the traditional isolating switch is not provided with a protective structure, which is easy to cause accidental contact, and thus needs to be improved. Utility Model Content
